description

Specific coupler for applications where the directivity and optical power are the most important characteristics.
With a modified technology derived from the standard HD couplers these component offer a significant improvement of service life particularly in UV region where high power is a challenge.

These couplers can be used at all wavelengths guided by the fibre with almost no change in coupling ratio.
Due to the technology based on wave front division, they are only slightly sensitive to modal injection.

   
 
 

TECHNICAL SPECIFICATIONS

 Wavelengths : 400 to 1625nm (other on request)
 Fiber type : GI50/125 (other on request)
 Power handling @420nm : 2W (improving the service life in high power fluorescence applications)
• Port configuration : 1x2
 Coupling ratio : 50/50 (best ratio for this application with our technology)
 Directivity : > 50 dB (fiber GI50/125)
 Insertion loss : < 3,7 dB (in round trip configuration (Port 1 to Port 2) : ILoss < 6,5 dB
(can be lower than 6 dB if not used at fully filled stage))
 Uniformity : < 0,7 dB

 Temperature range :
Operating : -20°C / +70°C
Storage : -40°C / +85°C

 Packages :
08 : 45x7x8 mm Black loose tube 900µm
43 : 80x10x8 mm Black jacket 2,8mm

Product made to be used in round trip configuration.
Fibers are protected with black loose tube 900µm in order to avoid noise by external light.
One port is dedicated for injection and identified by a blue marking.

Note: There is no established standard for multimode components metrology. Values can vary substantially according to measurement bench set up (laser, diode, detector, etc.) Customers must check adequacy of performances on their system.
